Onin Tsuba with two overlapping lozenges, or interlocked diamond shapes. Iron and brass. Sukashi and ten-zogan technique. Muromachi period. Diameter: 81.0 mm; Thickness at seppa-dai: 3.2 mm The symbol of two overlapping lozenges (or, interlocked diamond shapes), presumably a family crest (kamon) may be deciphered as chigai kuginuki (nail extraction tool => 'conquered nine castles' ) or as chigai bishi (overlapping lozenges). Similar symbol can be found at Butterfield & Butterfield. IMPORTANT JAPANESE SWORDS, SWORD FITTINGS AND ARMOR. Auction Monday, November 19th, 1979. Sale # 3063], №94 with the following explanation: " This was the mon (crest) of the Yonekura family of Kaga Prov., at Kanazawa". An interesting insight is provided by Robert E. Haynes at Important Japanese kodogu, gaiso and works of art. San Francisco, April 9-11, 1982. Robert E. Haynes, Ltd., № 36 (see photo): "This would seem to be the Yonekura family mon. They were Seiwa-Genji Daimyō family made noble in 1696 and resided in Kanazawa in Kaga". Would it be possible that this is a late 17th century Ōnin tsuba?  

Iron tsuba of round form adorned with the design of stars, wild geese, floating blossoms, leaves and tendrils realized in brass inlay. The inlay technique includes suemon-zōgan and ten-zōgan. Two smaller openings (hitsu-ana) surrounded by a scalloped brass border. The seppa-dai border inlay is missing, as well as a few other fragments of inlay on both sides. Sword cut at 12 o'clock on the reverse. A tsuba with a strong autumnal connotation, which once belonged to a great battle weapon. One of only three known jūyō Ōnin tsuba. Translation of the paper, issued by the Japanese sword fittings (tosogu) examination board: Designated as jūyō-tosogu at the 34^th jūyō-shinsa held on April 14th 1988 Kaki-karimon zōgan-tsuba (花卉雁文象嵌鐔) — Tsuba with zōgan design of flowers and wild geese. Mumei: Onin (応仁) Tokyo. Nakasono Tokumi (中園とくみ) Measurements: height 9.5 cm, width 9.4 cm, thickness at rim 0.35 cm Interpretation: marugata, iron, brass zōgan, two hitsu-ana Time: end of Muromachi Explanation: Ōnin-tsuba are thin iron ita-tsuba which show a brass zōgan ornamentation. All of them are mumei and there is the theory that they were made in the Onin era (1467-1469) although today more and more the theory is accepted that they are in general late Muromachi period works. There are two kinds of brass zōgan interpretations: One depicts irregularly arranged tachibana branches, wild geese, chrysanthemums, flowers, or karakusa for example, and the other one shows punctual zōgan elements, which are referred to as hoshi-zōgan or ro-zōgan, and concentrical zōgan elements between the nakago-ana and the rim. The latter interpretations might also be accompanied by simple ko-sukashi in the form of butterflies, clouds, hats, or stylized mountains. This tsuba is a typical work from the former category. It is large and feels massive and the powerful and impressive zōgan and the excellent iron make it a highly tasteful piece.

Iron tsuba of round form with design of double crossbar and two family crests (hikiryo-ni-kamon) in openwork (sukashi). Squared rim. Copper sekigane. Owari school. Early Edo period: Late 17th century (Kanbun / Enppo era). Height: 80.9 mm. Width: 80.8 mm. Rim thickness: 5.0 mm. Center thickness: 4.6 mm. Provenance: Sasano Masayuki Collection, № 172: "A paulownia and a clover are diagonally opposite two crossbars. This expressive design suggests a Higo origin, but the iron and the finish are certainly of the Owari school. Work of this nature may have been influenced by Hayashi Matashichi (1613-1699)."

Iron tsuba of slightly elongated round form with design of wild geese and drops on pampas grass (masashino) in openwork (sukashi). Rounded rim. Copper sekigane. Owari school. Early Edo period: early 17th century (Kan-ei era). Height: 78.8 mm. Width: 76.3 mm. Rim thickness: 6.1 mm. Center thickness: 6.4 mm. Provenance: Sasano Masayuki Collection, № 169. A description of musashino symbolism can be found at Symbols of Japan by Merrily Baird [Merrily Baird. Symbols of Japan. Thematic motifs in art and design. Rizzoli international publications, Inc., 2001]: Musashino - "the plain of Musashi - a large expanse in the Tokyo area, was celebrated in poetry for the grasses that grew there before the recent era of industrialization... The use of Musashino themes was particularly common in the Momoyama and Edo periods". Pampas grass with dew drops and wild geese in flight collectively provide strong autumnal connotation.  

Iron tsuba of round form inlaid with brass, copper, and shakudō wire fastened to the surface with metal staples (mukade-zōgan); Scalloped brass inlay around the rim. Early Edo, 17th century. Height: 84.8 mm; Width 84.8 mm; Thickness at seppa-dai: 3.7 mm. Weight 161.6 g. Design is thought to resemble a centipede. "Centipede-like inlay (mukade zogan) of alternating iron and brass staples produce an appearance that was particularly favored by Takeda Shingen (1521-1573), one of the most powerful warlords of his time. The centipede is sacred to Bishamon (God of War) and especially propitious for a warrior. Shingen type, 16^th century.” [The Peabody Museum collection of Japanese sword guards with selected pieces of sword furniture, by John D. Hamilton. Photographs by Mark Sexton.

Shingen school (or style) tsuba of round form with an iron core of spoked-wheel shape, with its centre covered with a copper plate decorated with star-shaped punch marks. From this copper plate outward, the body is formed by brass and copper wire (flat and twisted) in a weave pattern. Both hitsu-ana are outlined in brass with a raised rim. Copper sekigane. Unsigned. Edo period, 18th century. SOLD   Height: 98.0 mm, Width: 97.4 mm, Thickness at seppa-dai: 6.0 mm. Weight: 290 g. NBTHK certificate №436696: 'Hozon' attestation. Citing "JAPANESE SWORD-MOUNTS IN THE COLLECTIONS OF FIELD MUSEUM" by Helen C. Gunsaulus, Assistant Curator of Japanese Ethnology. 61 plates. Berthold Laufer, Curator of Anthropology. Field Museum of Natural History, Publication 216, Anthropological Series, Volume XVI; Chicago, 1923; p.45: "An unusual group of tsuba popular in the late sixteenth century and afterwards is made up of those guards known as Shingen tsuba, a name which was derived from a sixteenth-century warrior, Takeda Shingen (Takeda Harunobu, 1521-73), who is said to have preferred this style of guard, as it combined strength and lightness. Under the category of "Shingen", four different types abd generally listed, though a fifth appears in the drawings in the Boston Catalogue of Okabe Kakuya "Japanese Sword Guards" (p. 21). It is square, that form which is said to have been used in Ashikaga days for scaling walls, the sword having been set up as a step. [...] The following descriptions include, however, the Shingen tsuba usually met with.

1. So-called Mukade ("centipede") tsuba are made of iron in which a centepede is inlaid in brass or copper wire. Mukade tsuba of Myōchin and Umetada warkmanship have been found with the inscription, "Made to the taste of Takeda Shingen".
2. There are those of solid iron, with need centers of brass, to the edges of which is affixed a weaving of brass and copper wires which is bound to the foundation disk by a rim, usually decorated simply.
3. Another type is of solid iron, bored at intervals and laced with braided or twisted wires of copper and brass.
4. The fourth type is a chrysanthemoid form, chiselled in open work and laced or woven tightly with copper and brass wire."

I believe that my tsuba [№ TSU-0338] belongs to the fourth type. However, this particular specimen does not conform with the description of Shingen tsuba as combining strength and lightness. Its weight is 290 g, which tells us that most probably it had purely decorative function (as most tsuba in Edo period). A somewhat similar design can be found at wikimedia. A look-a-like tsuba is illustrated at Compton Collection, Part II, p.p. 26-27, №54. It is dated ca. 1700. It was in a box with Sato Kanzan inscription, and had NBTHK certificate attesttion of 'Tokubetsu Kicho'. Price realized: $5,280.
